DRIER.

SPECIFICATION forming part of Letters Patent No. 779,264, dated. January 3, 1905.

A li ati fil d December 15, 1903. Renewed October 28, 1904. Serial No. 230,335.

To all whom it may concern.-

Be it known thatI, OHARLEs HAYES GAsPAR, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Driers, of which the following is a full, clear, and exact description.

This invention relates to a drier that is convertible easily from a drier heated by hot air to one in which the heating is done by steam.

A further object of the invention is to provide means when the drier is used as a steamdrier to remove the condensed steam or water from the drier without interfering in the least with the drying process and at the same assuring this removal.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a broken view, mainly in section, of the improved drier; and Fig. 2 is a section on line 2 2 in Fig. 1.

In the views the usual end plates 10, with the inclosing plates 11, form the usual casing, and on the outside of the plates 10 on either end are secured the rollers 12, on which rest the pulleys 18, thereby providing a ready means for the adjustment of' the revolving heating apparatus without its resting on the end plates 10. This construction is well known and is not considered essential.

On the inlet end of the drier the pulley 13 is placed on the pipe 14:, which is provided with a stufling-box 16, through which enters the feed-pipe 17, the flow through which is regulated by means of the valve 18. The heads 19 on either end are connected, by means of the angle-irons 20, with one another and with the rings 21, the whole forming the structure of the revolving drying apparatus and agitator and this structure insuring stability.

The heads 22 provide means for fastening the ends of the tubes 23, these tubes serving to carry the heating medium. The head.19 on the outlet end of the drier terminates in the pipe 24:, which can be arranged to lead into the box 25, (shown in dotted outline in Fig. 1,) or when used as steam terminates in the chamber 26, which is provided in turn with a stuffing-box 27, through which projects the pipe 28, the uses of which will be hereinafter described.

Within the pipe 2A are arranged the tubes 29, extending up into the head 19 and being bent, as at 30 in Fig. 2, so that when the drier is revolved all condensed steam in the form of water that settles in the lower part of the head 19 on the outlet end of the drier is scooped up by these pipes 29 and emptied into the chamber 26, after which itis drawn off through the siphon 28 and can be led off into any suitable trap 31. This revolving heating apparatus inside the casing can be propelled by suitable mechanism connected to the gear 32 and by its revolving thoroughly dries moist material, such as grain, that is fed into the inlet portion 33 and emerges on the lower end through the trough 34.

It will thus 'be seen that I have devised a drier that is preferably used with steam as a heating medium, but can be quickly converted into a hot-air drier, and one that when it is used as a steam-heated drier provides a simple and positive means for withdrawing the condensed steam and water from the drier.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A drier comprising a casing, a revolving drum in said casing, an inlet and an outlet to the casing, an inlet on one end of the drum,

an outlet on the opposed end of the drum, a pipe ,feeding steam to the inlet end, means operated by the rotation of the drum to remove the water or condensed steam from the outlet end of the drum, a chamber on the end of the outlet to receive the water from the removing means, and means adapted to withdraw water from the chamber.

2. A drier comprising a casing, a revolving drum in said casing, an inlet on one end of the drum, an outlet on the opposed end of the drum, a pipe injecting steam into the inlet end, a series of pipes in the outlet end, these pipes having their inlet ends projecting in the direction of the rotation of the drum and having their outlet ends opening into a chamber, and a siphon arranged to empty the chamber.
